It operates vegetable, fruit, pizza boxes, Toshiba bases, and any boxes with a specific forme.
Its production rates reach up to 7000 boxes per shift.
Equipped with an automatic line to pull the sheet to the hooker press.
Mini Line Machine:
There are two machines used interchangeably for printing:
Mini Line Printing Machine 1984 France.
Mini Line Printing Machine 1986 France.
Capable of printing 3 colors and regular detailing.
Production rates of this machine can reach up to 12,000 boxes per shift.
Stitching Machines:
4 machines by Bahmuller Germany, 1988 model.
Machine production rate ranges from 5000 to 7000 boxes per shift.
Binding and Packaging Stage:
Binding is done using 0.6mm chamfer stitching machines according to the number of boxes required by the customer. The product is then packaged using stretch machines for the product to reach the customer in an orderly and clean condition.
Starch Kitchen:
It is an automatic system for manufacturing the starch paste used in gluing the layers of the product during manufacturing. The paste is manufactured from corn starch, caustic soda, and borax in specific proportions and at a specific temperature, working efficiently.
TCY New Printing Machine:
Taiwanese-made model 2022, a 5-color printing machine. Top printing, detailing, circular crushing, and automatic gluing - 3-phase electricity & 380 volts power capacity.
Size: 120 cm × 250 cm.
The production rate of the machine can reach up to 250 chicks per minute. -
- Martan Machine:
This machine has a single-color printing unit, but it uses oil-based inks instead of water-based ones. After printing, these chicks are transferred to the regular knives stage, which matches the length and width of the chicks.
Its rate is 5000 - 4000 boxes per shift.
Manual Gluing Stage
The boxes produced and printed in the previous production stages, except for the machine can be glued either using manual gluing with a brush and white glue or using automatic gluing TCY
[ Semi-automatic gluing machine Machine model GSG-10
This machine is characterized by its performance quality, where it can glue all types of cardboard, whether 3 layers, 5 layers, or even duplex cardboard. It also stands out in that the amount of glue used in gluing can be controlled by the air pressure used.
Company Laboratory Section:
The Moharam printing press includes a laboratory equipped with the latest devices for testing all types of paper. Examples of these devices:
1- Compression Resistance Measurement Device Compression Test
- Used to estimate the load-bearing strength of the corrugated box against external pressure forces in unit kg . This represents the best test to determine the quality, capacity, and ability to handle, store, and stack ready-made boxes.
2- Tensile Strength Estimation Device Tensile Strength Test
- Used to estimate the maximum tensile strength of paper and cardboard in both the longitudinal and transverse directions. This specification applies to both paper and cardboard materials and does not apply to multi-examination corrugated cardboard.
3- Ring Crush Estimation Device Ring Crush Test
- Used to estimate the resistance of the edge of the corrugated cardboard [Kraft and Fluting only] to compression. This feature is the most important measure of the performance of corrugated cardboard and the quality of the final product.
As corrugated cardboard packaging is subject to loads, it must be resistant to compression, and this represents the best choice for cardboard packaging manufacturers.
4- Paper Perforation Device Concora
Used for perforating flute paper, followed by measuring the resistance force on the Ring Crush Test device used in manufacturing multi-layered corrugated cardboard in the multi-layered laboratory. Then the measurement is taken.
5- Burst Strength Estimation Device Burst Strength Test
Used to estimate the explosion resistance of paper and cardboard due to increased hydraulic pressure and is applied to both paper and cardboard materials ranging from 170 to 1400 kilopascals.
6- Hardness Estimation Device Hardness Test
Used to estimate the twisting strength and flexibility of duplex cardboard only.
7- Thickness Estimation Device Thickness Test
Used to estimate the thickness and specific volume of all paper material varieties.
8- Degree of Sizing Estimation Device Cobb 120
Used to estimate the paper and cardboard's water absorbency.
The company also has several devices for environmental measurements, including:
- Multilevel Temperature Device with Condensers.
- Bacterial Incubator.
- Thermal Combustion Furnace.
- pH Measurement Device.
- TDS (Total Dissolved Solids) Measurement Device for Water Quality in Geysers.
- Digital Water Bath.
- Digital Water Bath.
- Electric Furnace.
- Hofmann Funnel.
- Hofmann Funnel.
- Air Pump.
- Water Distillation Device.
- Mettler Balance.
Mouharam Printing Company is considered one of the leading and pioneering companies in the field of manufacturing various packages to support packaging processes in Egypt.
As it is known, the processes of packaging and selecting the appropriate package for a product are based on several scientific principles, including:
Containment
Protection
Sales
Economic factor
In Mouharam Printing Company, the required package is designed to suit the type of the intended product, ensuring that the design aligns with these four aforementioned factors. Then a prototype is created for review, facilitating an exchange of artistic and intellectual contributions between the designer and the product's ideas, ultimately leading to the most suitable results.
The technical departments in the company play a vital and fundamental role in the printing process, being involved in preparation, design, and execution of various designs for covers, labels, packages, and brochures serving different sectors of the Egyptian industry such as food, consumption, pharmaceuticals, textile, and electrical industries, as well as various types of durable goods.
These technical departments' operations, which precede the printing process, include design, image assembly, color separation, montage, and preparing printing plates. All of these operations are conducted using a variety of computer-based devices and equipment to achieve high artistic quality in the printing production.
The printing plates, in their various types, are prepared, including pre-sensitized aluminum plates for wet offset printing (flat printing). Also, photopolymer plates are prepared for prominent printing in two types: flexographic printing for corrugated cardboard and dry offset printing in the shampoo factory.
After the approval of samples by esteemed customers, the execution is carried out immediately in one of the company's various factories, according to the type of the required package.
